Wow, are "Christians" so often willing to justify their actions and sacrifice what is their unique place in the world to instead live like the world does.
But lets get this straight about God as written about in the Bible: God doesn't condone actions that are contrary to his ethic of sacrificial and selfless love. God also doesn't do things or condone actions contrary to the covenant that is being established, especially as a means to establish that covenant.
For example, he is not going to have you shoot people to establish peace. He is not going to have you rip someone off to establish a financial blessing. He is not going to have you live and have sex with your girlfriend/boyfriend to establish a marriage (or re-establish a marriage).
